simpleplay 1.8.2

simpleplay 1.8.2: fixes and minor adjustments: the “–” button, playlist saving and list details.

Fixed

• The "–" button (and "Remove from the list" in the right-click menu) did nothing since 1.8; it now removes the selected tracks.
• The floppy-disk button no longer overwrites an old playlist without asking. A playlist is only "the open one" while the
  list still comes from it: loading a folder or files into an empty list forgets it, and so does a playlist file that no
  longer exists. The first save asks where and under what name (proposing the folder's name).

Changed

• "Music and playlists" shows which playlist is open (or "not saved"), the save button names it, and there is a new
  "Save as…" button. Saving always says where it saved.
• The track that is playing is marked with a dot in the list; the list scrollbar is slim and rounded; list rows light up
  under the mouse; dropdowns in the side panels have their own arrow.

Everything in 1.8 and 1.8.1 is included: see the 1.8 notes.
